Dismounting External Drives mystery

Hello, I’ve got a problem recently with my external disk drives vanishing. I’ve had theses 2 external HDs for over a year now, and this behavior started last week for no apparent reason! It really is making me insane because to get them back I have to power them on and off sometimes a few times, and sometimes I have to unplug and replug the cable (one’s firewire and the other is eSATA…Does anyone know what the hell is going on??? It happens at least 6-8 time in a 10 hour day..I don’t use sleep/hibernate/standby at all. If I’m not working on it, the computers get shut down. It’s really irritating because I changed nothing at all, it just started to do this…Sorry to be repetative. :face_with_spiral_eyes:

setups are as follows

CPU1
Vista Ultimate x64
iomega 500 GB connected with eSATA cable
NFTS

CPU2
XP pro x64
Maxtor One-Touch III 300GB connected with Firewire
NFTS

So, you didnt install any software or hardware that may have started these drives dismounting…no windows updates..no bios updates youve installed ? Something small you may have forgotten..maybe power management ?

good ideas

Hi, those are all good ones, but no, none of the above. I don’t enable the power management features, I just shut them down unless they are rendering overnight(s). And now, the problem has at least shown a decrease in occurances (for no known reason, too!?)

Thanks,
JR
